It is very possible that the relay had just shorted out and over heated.But you would want to look closely at the wires under the fuse block to make sure they did not over heat and cause the insulation to melt away.Replace # 37 with a new one and try it ,if everything else looks ok.

code - po442=evap leak medium detected

code-po456=evap leak small detected
look at fuel cap or leaks in rubber hoses

Google this asd problem, there is a lot of information on this problem. I would look for a short but would not want to remove the complete harness.. If you do this take pictures of the harness and all connections before you start.

Most likely fan motor over load. Recommend replace and recheck.

check to see if the fan spins freely if it is sluggish or stuck replace the fan motor as it is drawing excessive current and blowing the fuse.

Pls be more specific, doe's this fuse keep blowing or what? Fuse blows and your car won't start. I have a 2004 GTC and the #8 fuse kept blowing, had to replace the starter, (it was pulling 80amps instead or the normal 30-35) once the starter was replaced, no more starting issues and the fuse no longer blows. Hope this helps, good luck

Fuses pop because it is breaking the direct line of voltage that is being selected...anotherwords...instead of when you turn on your radio and the incorrect amount of voltage that is being sent to the radio frys it, the fuse breaks/pops to stop the flow of voltage to the radio.

The problem seems to either be a bad relay or wires are touching somewhere in that system.
